Check a Dacia Sandero advert (free) →The Dacia Sandero has 2 known faults in our database, 1 of them rated high severity. The most serious are fuel system (delphi high-pressure fuel pump breaks down internally) and electrics (two owners of 2018 Sanderos reported starter failures). None of them makes the car a bad buy on its own; the risk is a seller who knows and says nothing.
That is a count of the faults we hold, not a reliability score. Popular cars get written about more, and a newer generation has had less time to show its faults.
No year is a write-off on its own. What matters is which serious faults a given year and engine can have, and whether the car in front of you has had them fixed.
Each one is set out in full below, with the symptoms, the typical mileage and a rough repair cost.
One owner each, in their own words rewritten as a line, and not counted in our risk scoring. A fault joins the list above once a second report or an editorial source backs it.
Sellers rarely admit these faults outright

They do not tell you whether this particular car has had the work: for that, put the registration into the free GOV.UK MOT history check, which shows a recall status where the manufacturer shares it, or ask a franchised dealer to check the VIN.
Contact between the positive battery terminal and the alternator could cause an electrical short circuit.
Put right by: Modify the wiring route and if necessary replace the alternator.
Drivers air bag may not deploy correctly.
Put right by: Replace drivers air bag.
Risk of a diesel fuel leak in the engine bay
Put right by: Fit a protective clip or replace pipe.
It has been identified that due to an internal defect within the drivers air-bag if the SRS system detects an impact/collision which requires deployment of the air-bags then the drivers air-bag may not deploy. Therefore there is a risk of increased injury to the driver.
Put right by: Recall all affected vehicles to check and if required replace the driver's air-bag with a new unit.
On a small number of vehicles the drive rotor at the ball join on the steering rod may break due to excessive stress.
Put right by: On affected vehicles check steering rack type and if necessary replace.
Recall data published by the Driver and Vehicle Standards Agency under the Open Government Licence v3.0. A recall listed here may not apply to every car of this model: the build dates and the registration check are what decide it.
An overdue cambelt is the most expensive thing a seller can fail to mention on a used Sandero. These are the figures UK specialists work to.
Generally 6 years or 72,000 miles (older variants were 5 years/72k). The water pump, tensioners, and idler pulleys must be replaced simultaneously.
Always confirm against the vehicle handbook. Intervals vary by engine, and several manufacturers revised theirs after failures in service.
No Dacia Sandero year is a write-off, but the Dacia Sandero (2012 to 2020) carries the most serious faults: fuel system. Year matters less than whether the specific car has had the known fixes, so check the history for them.
Ask the seller about the fuel system and electrics faults on this page and whether they have been fixed, with invoices. On the test drive watch for flashing glow plug or engine management light and engine not turning over when the key is turned. Read the MOT history for repeat advisories, then paste the advert into the free check, which reads it against its known faults before you travel. Check a Dacia Sandero advert →
The DVSA lists 5 safety recalls for the Dacia Sandero issued between 2016 and 2020. The most recent, from January 2020, is "The contact between the positive battery terminal and the alternator could cause an electrical short circuit". Recall work is done by the manufacturer, and GOV.UK says you will not usually have to pay for it. This list is by model, so it cannot tell you whether one particular car has had the work: the free GOV.UK MOT history check shows a recall status from the registration where the manufacturer shares it, and a franchised dealer can check the VIN.
Owners report 49.1 mpg on average across the Dacia Sandero engines with data, about 85% of the official combined figure.
